find user without sig (sql query+)

[Sculli]

SQL query god(s), once again I call upon thee!

One of my board rules is that every user must ad their game character to their signature. This is very important as the persons in-game reputations carries over to the board, and their board rep into the game.

Anyway, some users don't read the rules, some don't care, etc etc.

Ultimately what I would like is some sort of automated way to send all those who do not have anything at all in their sig a PM that says they do need to add their character name to their sig.

In the short term a query that would return the user names of those who do not have a sig of any kind would help, I would then manually PM those users.

Thanks in advance for your time and consideration.
